From McDonald's Shamrock Shakes to Krispy Kreme's green doughnuts, the fast-food and restaurant industries won't be holding back Friday when it comes to trying to cash in on what owners hope will be record spending by St. Patrick's Day celebrants.

The National Retail Federation predicts that Americans will spend more of their own "green" for this year's holiday celebrations — $5.3 billion — than in any of the previous 13 years since it started monitoring the holiday. That's an average of $37.92 per reveler among the more than 139 million people who are expected to mark St. Patty's. That's up from last year's $35.37.

The big winners, always always, are expected to be restaurants and bars, since the day is often celebrated with corned beef and lots of alcohol. Here's a list of some of the promotions being offered up by national chains:
